ACTIVE AND PASSIVE D.I. BOX | ANO ANG PINAGKAIBA

This video is about active and passive d.i. box kung ano ang pinagkaiba nila. Kung saan ginagamit ang passive at para saan naman ang active direct inject box. What Is a DI Box? Born out of necessity in studios such as Motown and United Sound Systems to accommodate the electric instruments emerging in the 1960s, direct boxes (also known as DIs, which stands for “Direct Inject”) began as a way to resolve a basic impedance mismatch between electrodynamic guitar pickups and sensitive studio electronics. Although many modern DIs are far more sophisticated than the original models, even now, the primary function of DI boxes is to take an unbalanced, high-impedance signal and convert it to a balanced, low-impedance signal. This allows you to run guitar and bass directly into microphone preamplifiers or to send signal over extended cable runs without losing volume and significant high-frequency information. Passive DIs Like the original models, such as Ed Wolfrum’s Wolfbox, modern passive DI boxes typically use a form of balun transformer to convert high-impedance signal to low-impedance signal. This style of transformer features electrically separate windings in the input and output stages, which isolate ground-level voltages and eliminate ground loops. The result is that signal is both impedance matched for a standard mic pre and free from ground hum originating at the input stage. Passive DIs are ideal for instruments with strong outputs, and both their low cost and durability make them the most popular kind of direct box. Active DIs The biggest difference between an active DI and a passive DI is that an active DI includes a preamplifier. This type of DI was originally designed to provide an extra gain to boost the weak output of some passive, single-coil pickups, but the extra gain is great for driving long cable runs, and many modern active DIs include advanced signal routing capabilities and higher headroom than their passive counterparts, making them an excellent choice for keyboards and instruments with active pickups. The circuitry onboard active DIs requires power, which can come via batteries, dedicated power supplies, or 48V phantom power, depending on the model. Also, because they are more technically complex than passive DIs, active DIs usually cost a bit more. thank you sa panonood at sana nagustuhan mo ang ating content.
